“Of course,” I said. “The second dagger we found in the tramp was Mrs. Renauld’s. There were two, then.”
“Certainly, and, since they were duplicates, it stands to reason that Jack Renauld was the owner. But that would not trouble me so much. In fact I have a little idea as to that.

“About five, I believe.”
“That will do very well. We shall just have time.”
“You are going to England?”
“Yes, my friend.”
